Finitism

Finitism is the idea that there are only finitely many numbers or things that exist. For example, if there were just ten numbers, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, then that would be an example of finitism because all of the numbers that exist are "finite" or limited to just those ten numbers.
